Analog circuits for sensors

This contribution is devoted to CMOS analog circuit design for integrated sensor systems. While today complex sensor signal processing tends to be implemented in digital domain, analog circuits still play a crucial role in sensor signal acquisition due to analog nature of sensory signals. Though sensor front-ends frequently employ analog circuits, e.g. for sensor signal conditioning and conversion, generation of bias and reference voltages and currents, and system interfacing, the most important circuit here -for both, on-and off-chip sensors -is the sensor readout, since it directly interfaces the sensor.
